RE: [PHP] Cache

This is not my intention :) I don't want to actually disable the back button, but just not allow to go back to a specific page. This is very common on sites that use ecommerce and don't want you to go back to the payment page right after you finished paying to avoider double payments. I can see this work on other sites. I can see the headers they send, and this is the message you get on IE when you use this feature : Warning: Page has Expired The page you requested was created using information you submitted in a form. This page is no longer available. As a security precaution, Internet Explorer does not automatically resubmit your information for you. To resubmit your information and view this Web page, click the Refresh button. Sincerely berber Visit http://www.weberdev.com/ Today!!!

Yes, it's called "User Control." People don't like you disabling features on their browsers. You can't disable the back button, the only thing you can do is open your site in a new window without toolbars, and even then not all browsers are going to allow you to do so, and some users will just hit CTRL-N and open your site in a new window *with* toolbars, defeating your code. -- S.
